Specification of Letters, Patent. Patented July 5, 1921.

Application filed m a, 1920. Serial No. 394,192.

- a valve in such manner that when the valve is raised, there is a minimum of obstructing parts, ridges or walls to interfere with the free flow of air through the valve seat and the valve guard. Another important object of the invention is to provide guiding means or ribs on the guard which are continuous and located over the body portions of the valves so that they do not obstruct the flow.

Another object of the invention is to secure a plate valvev constructed of one piece of sheet metal in which a continuous guiding flange is formed integral with the body portion of the plate by turning one edgesubstantially at right angles to the plate.

A further object of the invention is to provide a reversible late valve construction-for fluid pressure cy inders which may be used either as an inlet or as a discharge valve as desired.

- Further objects of the invention will hereinafter appear and to all of these ends the invention consistsof the combinations of elements, arrangements of parts and features of constructionsubstantially as hereinafter fully described and claimed in this specifica tion and shown in the accompanying draws ings in which,

Figure 1 1s a transverse sectlonal view of the valve construction on the line '1-1 of Fig. 2 is a perspective view of one of the valves.

' Fig. 3 is a partial bottom lan view of the guard on the line 33 of ig. 1 looking in annular concentric passage-ways B over which the valves, one of which is shown in detail .in Fig. 2, are adapted to seat. A guard 0 having passage-ways D bears at its center and at its peri hery upon the valve seat as indicated in ig. 1 and limits the lift of the valves. A suitable bolt E preferably has a head F, resting in. a recess in the valve seat, and has a nut H with a reduced portion G resting in a correspondmg recess in the valve guard for holding the parts together. The plate valves, one of which is shown in F 1g. 2, are preferably constructed of one piece of sheet metal and comprise a body portlon J in the form of a fiat ring, having one edge formed substantially at right angles thereto to constitute a continuous guiding flange K' integral with the body portion. The guard C as shown is provided with guiding means in the form of continuous concentric ribs L located over the body portions J of the valves and cooperating with the guide flanges K to guide'the valves and limit their lift. As indicated in Figure 1 the guide flanges K slide along the guiding ribs L as the valves lift and are returned to their seats.

The guiding ribs L on the guard C are provided with socket portions 0 to receive suitable springs P which bear on the body constructed to permit the guide flanges K of the valves to bear upon the outer portions ofv the guide ribs L instead ofupon the inner portions.

By locating the uide ribs L or L of the guard over the b0 y ,portions of the valves, they do not obstruct the flow of fluid and when the valves are raised, there is an ab sence of any obstructing parts,.ridges or walls to interfere with the free flow of the fluid betweenthe valve and the valve seat.

Furthermore, the valve plates-are accurately ,alined and guided in their movements.

In order that the entire valve construction may be reversible so that it may be used either as an inlet or discharge valve, a circular flan e Q is provided around the periph- 1 cry of t e valve construction, and this flange the nut H, which produces a as shown is formed partly by the 'seat A and partly by the guard C or C. The flange Q is preferably but not necessarily spaced equidistant from the two faces R and S of the valve construction, by forming recessed.

'the seat and the reduced portion G of the nut H rests in a countersunk portion of the guard so that by inserting the bolt from the opposite direction to that shown in Figs. 1 and 4, the head F will be located in the recess provided for the reduced portion G of practically flush surface in the face S.

I claim:

1. A valve construction comprising a valve seat having an annular port, a valve constructed of one piece of sheet metal and comprising a body portion consisting of a fiat ring, adapted to seat over said port and having one edge for! led at right angles to the body portion to constitute a guide flange,

a guard for the valve, and continuous gu1ding means on the guard located over the body portion of the valve and cooperating with the said guide flange to guide the valve and limit its lift. v

2. A valve construction comprising a valve seat having an annular port, a valve constructed of one piece of sheet metal and comprising a body portion consisting of a flat ring, adapted to seat over said port, and having one edge formed at right angles to the body portion to constitute a guide flange, a guard for the valve, and continuous guiding means on the guard located over the body portion of the valve and coiiperating with the said guide flange to guide the valve and limit its lift and springs within the guard exerting pressure on the body portion of the valve for returning the valve to its seat after it lifts.

3. A valve construction comprising a valve seat having a plurality of concentric X,

- centric ribs on said guard located over the body portions of the valves and cooperating with the said guide flanges to guide the valves and limit their lift and springs seated in the guard and exerting pressure on the body portions of the valves for returning the valves to their seats after they lift.

4:. A valve construction comprising a valve seat having a circular port, an annular.

valve constructed of one piece of sheet metal and comprising a body portion consisting of a flat ring adapted to seat over said port and having one edge turned at right angles to the body portion to constitute a continuous integral guide flan e around said edge, a guard for the valve aving a continuous concentric rib located over the bod portion of the valve for guiding the gui e flange on the valve and for limiting the lift of the valve and springs seated in said guard and bearing on the body portion of the valve for returning the valve to its-seat after itlifts.

In testimony whereof I have signed this specification.
